Description:
------------
This is the same bug as reported and fixed for PHP5
http://bugs.php.net/bug.php?id=27865 and 32107 , but is still present in 5.3.0.

PHP doesn't close STDIN,STDOUT,STDERR correct.

I have the same Issues on Ubuntu 6 LTS.

Reproduce code:
---------------
<?php

$stdout = fopen("php://stdout",w);

fclose($stdout);

/* This now fails..*/
fwrite ($stdout, "Test");

/* but this still works: */
echo "Stdout still open\n";

/*
 * Standard output is still open.
 * The process is therefore unable to detach from its terminal.
 * See PHP Bug #27865,32107 (PHP5, fixed)
 */

?>


Expected result:
----------------
X-Powered-By: PHP/5.3.0
Content-type: text/html

<br />
<b>Warning</b>:  fwrite(): 3 is not a valid stream resource in <b>/srv/www/wwwenv3.0/sbin/test_fork.php</b> on line <b>8</b><br />
Stdout still open

You're not closing stdout there. You're closing stream opened to 
php://stdout which is different to what PHP itself uses, a.k.a. STDOUT.

Ok, but i have the problem, that STDOUT isn't defined when i call php from cli.

My main problem is, that i want to damonize my php script and STDOUT,STDIN,STDERR wouldn't closed correctly.

Here is my test Script:

<?php

/* This now fails..*/
fwrite (STDOUT, "Test");
fclose(STDOUT);

/* but this still works: */
echo "Stdout still open\n";

?>

Here the Output:

./php -n test.php
